A comprehensive system will be developed to promote mobility, enhance cognitive function, reduce sedentary behavior, increase independence and encourage social inclusion. This novel system will have two distinct yet complementary features: monitoring and treatment that will serve as an "all in one system". The system will consist of wearable sensors and a proprietary developed application. The wearable inertial sensors will measure the acceleration and orientation of the feet during movement. The sensors will feed real-time data to the system, which will process this data using a set of proprietary algorithms enabling continuous monitoring of activity, gait and fall risk, and independence. In addition, designated applications for direct cognitive assessment and training of older adults in their home and community environment will also be used via the Smart phone or mobile tablet. The training, both physical and cognitive, will also include multi-user interactions .Data collected by the system will be processed and integrated to provide comprehensive feedback from multiple domains to the user, caregiver and clinician by way of recommendations and personalized treatment goals.
